Django model inheritance: Create a subclass using existing super class

Question

I\'m using multi-table-inheritance, and want to know how to create an inherited type from an instance of the superclass.

Using the example given in the documentation

Answer 1

Multi-table inheritance is just OneToOneField relation between Place and Restaurant.

place = Place.objects.get(id=1)               

# Create a restaurant using existing Place   
restaurant = Resturant(place_ptr=place)
restaurant.save()
